SPECIEIOATION forming part of Lettere Patent No. 514,709, dated February13,1894.

Application filed June 26, 1893. Serial No. 4 -'78,8 53. (No model.)

To all whom it may concern:

Be it known lthat I, THOMAS GREEN, a citi.

` zen of the United States, residing at Sioux "ence ybeing had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification. i

My invention relates to continuous brick kilns, and the object is toprovide flues to regulate the draft and progress of the res and toutilize the surplus heat of the burning chambers. v

My invention is a modification of my continuous brick kiln, for whichapplication, Serial No. 389,718, was -tiled on the th day of April,1891, and to which reference is respectfully made.

The invention consists, therefore, lin noveltyofconstruction,thearangement of parts and the combinations thereof, aswill be here- I inafter morev fully pointed out.

I have fully illustrated'my invention in the accompanying drawings,wherein- Figure 1 is aview of kiln in side elevation. Fig. 2 is anenlarged detail plan view, partly in section, of portion of kiln takenin line 7- 7, Fig. 3. Fig. 3 is a detaill cross-sectional view of Fig.2. Fig. 4 is an enlarged detail view of damper, used in short lines, asshown in Fig. 3. Fig. 5 is an enlarged detail view of damper, or checkdraft, used in the overhead flue, as shown in Fig. 3.

Referring now to these illustrations, wherein like parts are designatedby similar-letters of reference, o. a represents the outer walls of thekiln, b, b, the wall portion of the kiln between the main chambers andthe smoke chamber.

't' 114 are dampers, one being located at the inner end ofthe iiueC,Fig. 3, and consists of a cap, which may be `drawn up to Open, or letdown to close the draft. j j2 is another kind of damper used vin theshort iues'F. v

k k are fire holes located in the top of central iue G. They byregulating the damper the kiln, adapted to above, each being cap.

L is the smoke-stack of the kiln. Y

mm is the frame roof of the kiln.

A, A2, dto., are the continuous chambers extending around thel outsideof the kiln, and capable of being entered through the Openings X X, asshown in Fig. 1.

be fed and regulated from provided witha removable located in the centerc c, Fig. 2, are partitions separating the chambers A, A2, &c. n B isthe smoke chamber located longitudinally between the' chambers in thecenter oil the kiln, and communicating directly with the smoke-stack L.

C is a flue leading directly from each chamber of the kiln over the topof the chamber into the smoke chamber. The dampers i 4 controlling thistlu e, are so located that they may be easily reached and repaired whenout of order.

G is a continuous flue passing around the cent-er of this kiln betweenthe chambers A A2, &c., and above the smoke chamber.

F F are short iiues leading directly from every chamber A A2, &c.,intothe continuous are regulatedby the dampers j j2, duc., which are locatedinthe fiues F, near the iue G. By closing the damper in the iiue'C, thusshutting o communication with chambers ahead, the surplus heat is drawnfrom any chamber through the tlue F into the continuous flue G; thence,in the short tiues, it may be conducted into any desired chamber, andthere mingle with the heat in the burning chamber. Thus, as shown linFig. 3, damper t' is closed, shutting off communication between chamberA and the smoke chamber. The brick in A is burned and in A2 is burning,while in A3 and A4 the green brick is just set and ready to be fired. Itisdesired to conduct the heat from Apast A2 into A3 and A4. Dampers j,js and 32 are opened and j2, and the heat is drawn from A past A2 andintoA3 and A4, as shown by the direction of the arrows.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is t The combination in a continuous brick Intestimonywhereoflaffxmysgnatnrcin kiln, of a, series of drying chambers,e smoke presence of two Witnesses. chamber located between said dryingchanlbers, and draft flues leading from the outer 5 Walls of the dryingchambers over said cham- Witnesses:
